Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False

It is false.
false
Because of something called Isostacy-the gravitational equilibrium between lithosphere and asthenosphere, such that plates "float" at an elevation that dependes on the thickness and density. EX. Think floating ice cubes
False - the asthenosphere is a solid that deforms in a ductile fashion - it undergoes permanent plastic deformations. Further information: The statement must be false. Plastic is a solid, so if something is going to be considered a non-solid, it cannot be like a solid. Whether or not the asthenosphere is solid, one cannot argue that it is non-solid as a result of it having a characteristic of plastic.
True! :)
This is true.
Convection current occurs due to the difference in densities
false i think
No. You can use your experimental observations or do more research to formulate a new hypothesis. A hypothesis that is not supported by the experimental data, it is just simply an unsupported hypothesis.
It is true.
